Subject: [CPUFREQ] use deferrable delayed work init in conservative governor
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8217e4f4c93e5fb59bb3cd1e6135213889349f86;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[CPUFREQ] use deferrable delayed work init in conservative governor

Venki Pallipadi made a similar change to the ondemand governor a while
back (in commit 28287033e12463c8ff89f1ea8038783d0360391c). It seems to
work just as well in the conservative governor, leading to fewer wakeups
as reported by powertop.
